Theodore Johnson (serial killer)

In 1981, an argument began between Johnson and Yvonne after she wouldn't let him go to church for being "not dressed well enough".[4] Johnson then proceeded to hit Yvonne over the head with a vase, before pushing her out off the balcony from the couple's ninth-floor Wolverhampton home.[2][4] When brought to trial in Staffordshire, the judge described him as a "battered husband" who had suffered abuse from his wife, sentencing him only for manslaughter for the "provocated" murder.[1]

Eleven years after killing his first wife, Johnson was released from prison, and soon met Yvonne Bennett in Wolverhampton. The couple moved to Finsbury Park in north London together, with Yvonne giving birth to a daughter, but separated after Johnson discovered that she was having an affair. He began stalking Yvonne, and at one point had to be removed from the house by police days before her death. In 1993, while their 2-year-old daughter was sleeping, Johnson strangled Bennett with a belt at their home.[1][2] He then phoned the police to confess his crime and unsuccessfully tried to hang himself from a tree before giving himself up to authorities.[4]

At his trial at the Old Bailey, it was claimed that he suffered from depression and a personality disorder. He pled guilty to manslaughter on the grounds of diminished responsibility. He was found guilty and sent to a mental institution.[1][2]

In September 1994, Johnson was allowed out of the psychiatric ward for the first time on escorted parole, and in mid-1995, he was allowed to spend two days at a City and Guilds course on furniture restoration by himself. There, he met 51-year-old mother-of-four Angela Best, who had moved to Tottenham from Manchester, and they quickly began a relationship. Johnson was released by a mental health tribunal in October 1997, on condition that he notified the supervising doctors and social workers about any relationship with women he formed. However, he did not reveal his relationship with Best until shortly before her death.[2] During a visit by authorities to his Dartmouth Park home, a wood carving spelling out "Love" was found on Johnson's mantelpiece, but the object did not arouse any suspicion.[1][3]

In September 2016, the couple split up after Angela found out about Johnson's previous convictions in a detailed letter,[3] with Best saying that she had felt the "happiest" she had ever been after finding love with someone else, despite Johnson continuing to profess his undying love for her daily.[1] When he was visited by a social worker and psychiatrist on 8 December 2016, he was not found to be in a depressive state and still denied being in a relationship. Two days before Best's murder, he had another appointment, but it was called off because his social worker was sick.[1]

On the morning of 15 December Ms. Best decided to visit Johnson at his Islington flat to help with an appointment with the Jamaican embassy. Soon after entering the house, Best was struck at least six times with a claw hammer by Johnson, who finally strangled her with a dressing gown cord despite her efforts to defend herself. Hours after killing her, Johnson proceeded to throw himself in front of an express train at Cheshunt railway station, losing his right arm and left hand in the process.[1][4] While the medics were treating his injuries, authorities visited his home and discovered Best's body in the living room.[2]
